About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-10S
It features a SUS420J2 stainless steel rod and PT tapered ports. By turning the rear screw, you achieve a usable travel window of 155 to 165 mm, allowing precise end-position tuning without swapping out the entire actuator.
This adjustable-stroke design eliminates the need to bolt on external stops during commissioning or product changeovers. The extruded aluminum barrel includes sensor grooves on both sides, and because this SKU includes a magnet (-S), it integrates directly with AirTAC CMSE reed and DMSE electronic solid-state switches. Remember that the rear adjuster functions strictly as a travel stop to set deceleration, not as a lock to hold the load without live air pressure.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |

| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-10S Is Used
Precision End-Stop Tuning
Dial in the exact 155 to 165mm retract position during machine commissioning to perfect part seating without machining custom spacers.
Product Size Changeover
Quickly adjust the stroke window by up to 10mm on a packaging line when switching to a slightly different carton size.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-10S the Right Cylinder?
The 10mm adjustment window is ideal for dialing in exact end positions at machine setup. If your process requires true load-holding without continuous air pressure, a standard SAIJ will not suffice; you should explore the SAIL air-released lock or BSAI clamp-lock series instead. To replace an existing ISO 15552 cylinder, match the 80mm bore, 165mm stroke, 10mm adjustment, G3/8 port, and the -S magnet requirement.
Because the nominal stroke is 165mm, side-load risks are moderate, but the 25mm rod diameter and M20x1.5 rod thread provide excellent rigidity. For any application approaching or exceeding 300mm of travel, an external guide is recommended to prevent rod binding, though this shorter stroke handles offset loads well. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-10S FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw acts as a mechanical stop, allowing you to trim the effective stroke back by up to 10mm from the 165mm nominal length, creating a 155 to 165mm travel window. It sets the end position but does not lock the load without live air.
